The study by travel company Expedia asked 4,500 hotels worldwide to rank tourists on their behaviour.
Japanese tourists - seen as clean and tidy, polite, quiet and uncomplaining - came top for the third year running.
French travellers made amends on elegance - classed third - as well as for their discretion and cleanliness.
But the French were the least ready to try a new language, unlike US tourists who were most likely to swallow their pride and order a pizza, baguette or a paella in the local lingo.

US tourists also got top marks for generosity, as the biggest spenders and tippers. But they fell short on other counts as the least tidy, the loudest, the worst complainers and the worst dressed.

Britons came second for their overall behaviour, politeness, quietness and even elegance - second for dress sense only to the Italians.
But in Europe, the British were seen by the hoteliers as the worst behaved. Jonathan Cudworth, the head of product marketing at Expedia.co.uk, said: "Being voted the worst tourists in the world by our closest neighbours highlights the fact that the 'Brits Abroad' moniker is a label we still haven't managed to shrug off."
